Why 10-Year Sealed Lithium Smoke & CO Detector Installation Triggers "Subject To" Appraisal Conditions
When a residential mortgage appraisal is completed under State Smoke/CO Overlays, any deficiency involving 10-year sealed lithium smoke & co detector installation shifts the report from "As-Is" to "Subject To" repair or inspection. Unlike general home inspection negotiation items, an appraisal condition tied to 10-year sealed lithium smoke & co detector installation is a hard underwriting gate that must be resolved and verified—typically via Fannie Mae Form 1004D / Freddie Mac Form 442—before the lender issues Clear to Close (CTC).
